Idiot -- is it not clear by now that he's not going to do that?

Do you imagine that you're going to "corner" Herc somehow into
displaying some rigor? Do you enjoying chasing after that dollar
bill on a string?

Good stuff, Mike.

But in your YEARS of dealing with Herc, has the idea not occurred
to you that Herc is arguing in bad faith? That he is a TROLL who
is HAVING A BALL jerking around a dumb sucker for YEARS AT A STRETCH?

Has that idea not occurred to you, Mike?

It seemed a reasonable question. I ask for a proof of listability, and
you provide a proof that the width is infinite.

Leaving that aside, perhaps you're under the impression that this
process, copied from another posting of yours

---

Given a set of complete permutations w digits wide

eg

00
01
10
11

make 2 copies and append each of 0,1

00+0
01+0
10+0
11+0

00+1
01+1
10+1
11+1

and extended indefinitely, ultimately lists all permutations.

It's certainly an infinite list of permutations, but you haven't proved
that it contains all of them. Since it's infinite in length, you can't
go through them to check. Instead you need to identify an algorithm that
will allow you to take any permutation and determine, in finite time,
the finite number that defines its position in the list. With such an
algorithm you could then say that since you can identify the position in
the list of any permutation, the list must contain them all.

With a list of rationals constructed using a diagonal method this is
straight forward.

http://en.wikipedia.org/wiki/File:Diagonal_argument.svg

With a given rational expressed in decimal, you try multiplying it by
sucessively higher prime numbers until the result is an integer. Since
the original divisor must be finite, this will be achieved in finite
time. This gives you the two numbers that form the ratio. The number of
the position in the list is then just the number of steps through a
diagonal chart required to reach that pair of numbers (the red ones are
not counted, because the two numbers are not co-prime).

http://en.wikipedia.org/wiki/File:Diagonal_argument.svg

Since it's obvious that any pair of numbers can be reached after a
finite number of steps, this proves that all the rationals are in the list.

To prove that all permutations are in the list, you need to do something
similar. So far you haven't.

I can do it until I get bored, can't I? Sometimes it's not the
destination that's important, but the journey.

Well, there's plenty of abusive people around for you to waste
your time on, if that's your thing.

Sorry you have nothing better to do.
